WALTER- wmontrgor SAN FRANCISCO, CALIFORNIA, ASSIGNOR, BY MES1i'E .ASSIGIF MENTB, TO UNDEBWQOD GOMIBUTINGMACHIFE COMPANY, A COBPORATIU'N OF NEW -hpplieationdileiit April 20,

T 0 all whom it may concern:

Be it known flint I,.WALTER Whoa-r, .u. citizen of Great Britain, residin at, San Francisco, in the county of San trancisco and State of California, have invented new and useful Improvements in Billing" and Computing Attachments to Typewriters, of. which the following is afspeclfioatiom.

The object of the pmsentinvention is to provide a. computing device which ooh he 4 attached to any stendm'd'typewriting mo 7 chino for the purpose ofjconipufiiug. both; vertical columns and horizontal; or cross totals of the figures as th'eynre written By the t-ypewriting mnohine in 1 larger. number of columns for a. given width'tham hosliertofofe been accomplished;- fend alsoforvarying; the widths of the several columns, whiIeeEQnO- mizin co in doings).

Attacimtent.The drawings show the invention as a plied to an .Underwood type:

writing ac me, but it is to bcunderstood changes, it may be ap- Is termed with two notches 6, into either of which canspnnga bent sprin arm 7, thereby yieldingly maintainin sci bar in either of two' positions. The 'ongitudinsl movement-of this bar, in the manner to be present 1y described, simultaneously connects all the numeral key levers with the computing meQh-i anismr To move said bar longitudinally, its

other end is formed-with a recess 8, into which extends an :irm 9 on arock shaft 10, (Fig. 5) to which'fis secured a lever 11, to one end of which is connected a hanger hook 12 which normally enter-s n. hole 13' in collar 14 on the lever 15 of the shift key 16 of the machine. The machine shown is what is known as a. shift key machine, in which each of the figure and letter type bars A, B carries two type, of which one 16' prints normally and the other 16 only when the shift key is depressed. All ofthe nine digits alre arr ed in the type-writing machine to corresponc to what is known as the lowcr case characters of the top row of keys 13, so that they may be printed by said keys withontusing the Shift key. Since some other character than 0. numeral is also carried on each numeral type bar, therefore, if theshift keyis used, and a numeral key operated, said other character is then printed. It is therefore desirable at that time to throw the com uting mechanism out of action. Upon eprcssing the shift key 16, the slide bar 5 is evidently moved to the right, and, as will presently appear, this has the efi'ect of automatically disconnecting the numeral key levers from any port of the computing mechanisnn so that when any numeral key is'used for the purpose of writing an upper case character 16 this is always done without the actuation of the computin mechanism. By the return of the shift ey, said slide bar 5 is moved to the left, which then a'gain connects the computing mechanism with the numeral keys,so them is depressed the computing mechanism will be actuated. Through apertures 17 in said slide bar 5 ass links 18, one for each numeral key, avinghook-sha. longer ends adaptedby the'movement 0 said bar to be movcd'into or out of engagement with upertured collars 19 secured u nu keys e i nk 1. 3s on ect its upper end to a bell crank lever 21,-,snother arm of which is connected to a wire rodi22, all of-said-nine-coiinb'cting rods 22 passing through a ring 23 (F i s. l, 8 and 10), secured wens hate 2, said rods being connected respective y to blocks 24 connected to levers 25 pivotallyl supported by said ring 23. Thus, upondepressip tiny one of the numeral keys, the on end of the corresponding lever 25 is over! toTth'ri ht The object of hrrdngciuerrt f is to se' ec tively control the action of the ap aratus', hereinafter'desorih'edl.

order to operate the nl'mi'cral keys \vithout octn dtingthe 'co'n'i uting' rnechhmsm Out k 'y 26 (FigsQIsndifi), thstem of whichhey is connected to'a bill orinnk lever 27, loose on the eer shaft 10, nnd h'ziying secured thereto a spring 28 afrd ipted tocng'age an abutment 29- extending 'frommn arm 28 depending from the loner-"11; A

A link 30 '(Fi 5) is'fco'rinectedito the lever 27 and to he he. or bar,1 2 -so that the first movement of said @Yc'r 27 has'the effect of withdrawing the holnlQ out of the hole 13 in the collar on the shift key lever. As this takes place, thespring 28 is compressed between the lever 27 o n d the abutn the levers-550i the nine nner,

when desired, there isf provided an ment 29. When said spr ng can nolon'ger yield, the lever 27, ooting fa'ga' nst the shut merit 29, causes the rockshaft '10 to rock, so that the slide hair 5 is moved to the right. against the actionpfitlie retaining spring 7, which then drops into the left one of the two notches 6, so that the operation of the shift key has now. no effect whatever upon the connecting or disconnecting .of the numeral keys with the computing mechanism.

To render the key connections again operative, there is provided an In key'31, the stem of which isconnected to the lever 11, so that the depression 'of said lrey 3l moves the slide bar 5 to the left The spring 28 then restores the key 26 to its normal position, so that the hoolr12 again entcrs this hole of the collar '14 on the shift key lever.

ontrallen-Secuicd on the right hand side of the frame of the typewigiting umchinc is a bracket 33, supporting a vertical plate 34, carrying posts 35," supporting a ride plate 36, having a circular series of iolcs, through which extend the ends of nine pusher re s 37, pivotally attached to the several hell crank levers 25 (Figs 6 and 7). Havin its bearing in the Jlatc 34 is a shaft 38, of a controller 39, whic 1, as will he presently described, is under constant rotational pressure. Stop bolts 40, of which there should be not less than ten, slide in 'a circular series of slideways 4i insai'cl controllefliivhichslide ways register with the pushet'rods, and sold bolts project-to the left of said controller normally, unduntil-they are displaced by the action of the pusher rods37. Anannnlar coiled s ring'42,- which surrounds the controller m a groove therein deep enough to intersect the slidewaysfor the bolts, and which is adapted to engage oneor the other of-two grooves 43 formed in each bolt yieldingly maintains the bolts in the positions to which they have been moved. When any numeral key has been operated, and the corresponding pusher rod inoved throu h the guide plate, its end impinges u on the end of astop bolt projecting from e left hand side of the controller and moves"said stop bolt-to the right from Fig. 6:=to:F-ig. 'fy'so" that its other endthen pfojects 'from the"- right hand side of said controller, and said stop bolt, thus projecting, willtherefore impinge against a sto wheel igl nnd'nrrestthe' controller, when he latter nfterbeing' -re-, leased by escapenientmechunism to bepres ontIy-clescrihecl, has rotated throu'ghan ange hudifiance which de'pends upon the position of the bolt-which has lost beemsiintnetei and therefore upon the particular pusherrod and the particular numeral key levelwhich have last been operated. When the controller so rotates, the progeeting end-of the lust previously projects stop" bolt is then by means of a. wedge 45 on theiplateB i, and located in the path of'the projected Stop bolt, returned to its "normal position, in which it projects from said controller the left'instead of to theright, and it isreteined in that-position b the nnnularcoiled-spifi 1ixm7mnent. eeured upon the front side of said plate 2 is a, gnidonray 46 forvsistem 47 (Figs. 6 and 7), theother end'oi rtihiohis pi votally connected to a lever 48 piv0 dat' 4%) upon the ring 23,tothe otherarm of which lover is secured a spring 50, which normally tends to draw said arm to the left, and therefore said stemto the ri ht. Said stem carries a disk 51, and all of t \erods22-pa'ss through holes in said disk; i

When any nnmeral key has been operated, anzl=thereby the corresponding rod rnoved to the left, the block 24 bywh-i'ch it is conm'ctedto the bell crank la er 25mm abutsagminst said disk, a ndmr1"ies'said disk w itli it In the left, this melting the lever 48. i The long arm of said lever is connectedat its ex treihe end by 1link52 with an arn'1*53,on an' eseapement-shnft 54, so that, byiseidmovement of said lever, said escapement she-ft is rocked. Said escupementvshaft-carries, aidjustnbly two disks 55, 56, spaced-sports short distance, and having respectively formed in' their bevelled edges notches in: recesses 57, 5S,ofl'set from each other, Figs.

' 8 and-9. Throughisaid plnt'e'te' possess stop shaft 59, which on the left side of said plate 34,"curries the befoi e-mentioned stop wheel =14, which is star-she ed, having points, any of-which'is adar'p' 'to'lie in the path of a"bo lt 'inthe controllei' ivhihhhas 7 been projected 'to' the' i'ig'lit enemas; saiid controller ii said "shift is their itself held fast and no'n rotutii lei Secured u 'on' the end of=said;'stop-sligi ft' -upon the'rig 1'. hand sideofth'e plntegtiisii s'rge 'ster'w'heel 60, lmving the some nurhlietof-points 'as the wheel -44, a point' of which; sturwliel'hdrmally' abnts iigainst'the first or rear disk 55. Therefore,when an numeraldieydias been actuated, and there ythe escapement' shaftorocked, thediskfifi is thereby'inoi d until the notch s'rtherefn c'oms'op site to the point of the large stqir =Whel- 68',- which "izun' th eri 'immdilitelf plies 't'tlii'ou li rerhisseimme new doe's'} hemes-as as 'alree'dy 'inentioned;-'=the :csptr'sner sli'ziffii' nrideb constant.- i'ota-tionnl- 'ressuio," sir-that the} preyiously "proicted 'olt is pgeesisg' -ng n inst-11v point'ofthe'hliogwheel fi i, ending to turn' it, nndthe 'shs "59,lihd the wheel 60."

It will thus be seen that the extent of move- 'mcntof the controller shaft is dependent upon the angular position, relatively to the stop whech'of the pusher rod octuuted, and

therefore upon the particular'numerol key which is operateds v Driwing.It has been already inentionegl that the controller shaft is under constantrotational pressure, tending, to rotate said shaft whenever released by the escapementmechanism. This rotational pressure is de-' rived 'from any suitable motorg'nncl :for the purpose of illustration I have herein shown an electric motor 61, Figs. 1 and 19::md 21..

The shaft 62 of said motor has secured there-s P on a head 63, to which are pivoted three weighted governor arms 64, Fig. 21 the ends of said arms being adapted to bear against the inner surface of a cup-shaped head 60 secured on. a shaft 67, so that said arms rotate sai shaft by their friction against said inner surface. Said shaft has secured thereon a bevel gear 68 which meshes with a bevel eer 69 on a shaft 70 which extends through libe plate 34, and carries on its outer end a gear wheel 71 Figs. 19 and which meshes with an i 1e wheel 72' which in turn meshes with a, ear wheel 73 upon the controller shaft. ft. is by this means that. the controller shaft. is given aconstant rotational pressure, olways In the same direction, ro-

toting the shaft whenever it is released.

In order to vary the amount of friction transmitted from the rotating shaft, there are provided sprin 's 76, one attached to each governor arm 64, the free end of the spring being adapted to be compressed inwards by a r' e 7.7, the position of which can be adjuste in a. direction purallel-with the shaft 62 by means of screws 80, which screw through said ring and into arms 82 extending from the head 63. By shifting said I'll)", said springs are more or less compressed, and tend to variably reduce the pressure of the governor arms 64 against the head 66.

Computing mechanism.-'lhe carriage 74 of the .main computin mechanism C0111- prises end lates 75, 1, 11, end 26), partition; 3 0 at every fourth writing space of the typewriter, two longitudinal burs TS, ands. casing 79 enclosing the mechanism, cut. away to form a. longitudinal slot 81, through which the figures are displayed. This computing carria c is supported from the paper. carriage 83 by means of arms 84 extending from said paper carriage.

The main computing carriage is made justsufiiciently large to contain computing devices in a. series corresponding in length with. the by ewriting line of the machine. Upon the le t hand end of the frame of the machine is secured a. bracket 8? which supports a plate 88 Fig. 1, at a distance from the plate 34 not less than the length of the computing carriage plus the distance through which the paper carriage travels. Between said plates 38 and 34 extend two tubes 89,- 90, aligned end to end the outer ends ofiwhich are loosely mounted in socketc in said plates respectively. \Vitbin the tube 90011 the right extends a. square computing shaft 91, which, at the right hand end, passes through the plate 34, and has secured thereon means, to be presently described, for rotating said shaft 91, and, at the left hand end, is formed with a ring 92 of the same diameter as the two tubes 89, 90 and lying between the inner end of said said shaft being also formed, at the sides of said ring, with circular, hub-like are confined between the plates 88 and 34,

Upon said tubes, and within the carriage, travel a series of computing wheels 95, Figs. 13, 15, and ltieach computing wheel being formed in the middle as an internal gear wheel, having ten recesses or notches 96,

and the ring or hub 92 has, projecting there-.

from, two diametrically opposite pins 97, Fig. 18 which are edupted to enter any diametrically opposite pair of. the ten notches 96, nndthus. act as a. master wheel to directl rotate thatcomputing wheel only .whic 1 is immediately over'said ring. The

tubes 89,90, are preferably-of such 1 th, and so. arranged, that the master whee is at, or substantially in the same vertical plane as, the writing point of the typewriter. Each computing wheel isformed with external gear teeth-98 which-mesh with gear teeth 99 formed at the side of -a corresponding 13 e wheel 100, said wheels being all loose y mounted upon-n-hollow' shaft 101 which extends between the-end plates of the carriage. Therefore, if the computing shaft is rotated 'throu 11 any given angular distance, the figure w eel, which is immediately over, or in the same vertical plane as, said master wheel 92on said computing shaft, is oorrespondin 1y rotated.

Horizontal or 30001254111] computing mahan'ism.-The horizontal computing mechanism' (Figs. 1, 11, 12, 14, 25, 25*, 25*) is, in general construction, 'similar' to the main computing mechanism. Thev description,

tberefce'e, of such parts of the main computing mechmiism as are also foundin the horizontal computing mechanism applies also thereto, correspond parts being indicated by the aflix x foi tie horizontal computing mechanism.

Addition and subtractim.-The computing shafts, 91, 91, have res ctively secured upon the ends projectin t rough the plate 3% bevel gears 103, 103", 4 igs. 1 and 19 which are adapted to be driven by a vertical shaft 104, having at-the .lower end a; bevel gear 105, driven by a. bevel gear 106 u on e horizontel shaft -10? having a. bev gear 108 driven by a bevel gear 109 upon the controller shaft. When said controller shaft has been released by the depression ofthe nu ineral key and rotates through an angular distance corres nding'to the numeral key deressed, sci rotation is transmitted to the vertical shaft 104 and thence to the shafts 91, 91", selectively in one or the other direction by means of sliding clutches 110, 110*, slidable upon said vertical shaft 104.- but. robot ing therewith; By means of a lever 111 the clutch is "adapted to he brought into operativeengagement with either of two bevel gears 112, 112, loose on the shaft 104 and always in engagement. with the bevel gear 103. If said lever is moved upwards, then the clutch 110 is moved into-engage ment with a clutch member formed w1thin the npper bevel gear 112", thereby rotating the romputin shaft 91 in the direction proper for addition. If said lever is nioved downwards, the clutch 110 engages the clutch member of the lower bevel'geor 112 and rot-ates the shaft 91'oppositelyto its former direction, causing the cbm unn wheels to subtract. If said later is moves to an intermediste position, the clutch 110 is out of engagement, and the computing shaft 91 does not rotate. Tnor'cler to'r etein the lever 111 in n'nypositio'n to which it 1n has been moved thereis'providedp. 1'00 113 Figs. 19 and 25 secured to the front go 0* the plate 34;, having three notches 114 adapted to selectively receive the edg'e of the lever. the levr having sufficient lateral spring. pressure to retain it iii either notch. lhe numerals 112, 112", 111", 113*, 114*, indicate parts for the secondary mechanism cor'respondin" to the pafts'112, 112, 111, 113. 114. of t e main mechanism.

Trans e1-mcchonimn-Tho transfer 'inechnnism is the same in"the secondary' com noting device as in the primary can nting mechanism, and I shall now dese'ri e the transfer mechanism of the seeonda'y, referring: to Figures 11, 12 51nd 14. pen the left side of each computing wheel 953mm: the periphery, is formed a singleliig or pin 115", I ig. 17 and each time that said wheel makes a complete revolution, said pin ongages one of five teeth of a transfer wheel 1'16". loose on a shaft 117, which wheel has fanned. on the left hand side, gear 'teeth 118 which mesh with the external geafr'teeth 98* on the right hand side of the next'comput-in wheel 95* to the left. Thereby saiid wheel on 'the left is artly rotated through one-tenth of a revh'ntion. Said transfer wheel 116" has elso formed thereon five concave sides 120* eiwh in an 'arc of a, circle of slightly greater dinn'ieterthan that of a. transfer cylinder or rolle'r l23", preferably of rubber or siinilun'resilient material, and has a hollow sqfia're rnefihllic core 122". There are a series of. siioh rollers 123*,"a1l

carried with the compnting carriage, one

hetween every two ed jn'centpartitions, 'z'i'nd. through the cores 122*, phsses a sqnare trn nsfcr shaft 121", which, as he'reinhftei' described, constantly rotates, Figs. 1, 4, 11 and 22.

\Vhen. by the ent ance of the lug 115", in the milnner jn s't iqfilaineil, the, transfer wheel '1 16" has ee'efi'movee through a dis lance corresponding to a part of one-tenth of'a revolution o'fthe computin wheel, it

is then in sneh 'a position that one of its projecting portions 194", between two adjacent concave sides, has been forcedinto sufficiently close contact with the constantly rorating trhnsfer roller 123* end is roteted with the latter, until its next concave side,

in turn, assumes a position over the rubber body of the'tra'nsfer shaft without being in contact with it. I

The corresponding parts of the'primsry computing mechanism, where they appear, are correspondingly numbered, but withouttlieexponent.

The transfer-shaft of the primary compulsing mechanism, at oneend'pussesthrough the plate 34 end "at the other end 'is'snpported by bearings inthe partitions, 'and the end late and partitions of the coinput- Jne' 'anism are cut away to pass the ro er 123. The shaft 121 'a'nd roller 123 :nm no relative longitudinal "movement, but 'hov 'ea constant rotary movement, which is derived fl-0 the electric motor, by inch 11's of a gear wheel 125 on'th'e shaft of'the notor meshing with an idle gear wheel 126 which in tu'zn meshe with a, gea wheel 12'? (Figs. 1, 19"c'nd 20) on afshaft 107 carry;

log a bevel gear 106 which meshes with is,

bevel 'gear105 on a vertical shaft 104' with which oo-operate ports similiar in their general oonstruotioh and tjrra'n'gefinent to those immediately cooperating with the vertical 'Shaft 104, except-as to, the fo'r'ih of the clutch sleeve 110, Fig. 22 which 'in this case only has a. pair of teeth instead of a number thereof on "each side the reason being that sii-id shaft 10% revolves constant-fly at n rapid speed, and, when 'the direction of coinputntion is changed, 'this most be done while i colitis-"6r for a, vsrinhle hinnb er of hit epen'tlent columns. The secondary mechanism is similar to tlmt of the main in the relation of the computing wheels to the figurewheels, the general construction, ofthe 'trnnsfer shaft, and the clutch nieclninism for shifting both the :co npnt'ing zindtmnsfer lnechzinism into any one or three positions to odd, to subtract, or Tor throwing; oht of operation.
